I tried Google Chrome last night. I love it. Except for one deal-breaker: the zooming functionality. IE7 got it right, and then Firefox 3 got it right--both browsers scale the whole page, including graphics and flash elements at an almost perfect ratio. Chrome does not scale graphics.
Working with multiple open windows and a 1080p display at home, this is a critical feature. When Chrome gets zooming right, I'll switch to Chrome.
